| 摘 要： | 研究了翅碱蓬生长区根际、非根际(根上部和根下部)沉积物和未生长区沉积物对应断面(亚表层、表层和深层)P的环境化学行为.结果表明,无论有无植物生长,沉积物总磷(TP)由表层(根上部)至深层(根下部)呈现逐渐减少的趋势且均以无机磷(IP)为主,有机磷(OP)含量最少,但植物生长区沉积物中总磷含量显著地增加,特别是根际沉积物 IP含量高达83%.对植物生长区和未生长区沉积物中IP的化学形态进一步分析表明,无论有无植物生长IP均以Ca-P为主,但在植物根际沉积物DP、Al-P和Fe-P均有显著增加,分别为未生长植物亚表层沉积物的3.5、8.3和3.7倍,从而导致活性磷比例增加,生物可利用性变大.

| Abstract: | The environmental chemical behaviors of P around rhizosphere sediment and non-rhizosphere sediment(upside root sediment and downside root sediment) in Suaeda heteroptera growth area and around the corresponding sections sediments(inferior surface section sediment,surface section sediment and deep section sediment) in no Suaeda heteroptera growth area were researched.The results showed the total P around sediment had the gradual reduction trend from surface section sediment(upside root sediment) to deep sect... |
